ABSTRACT Introduction Transvenous pacemakers are effective but carry significant short‐ and long‐term complications. Leadless pacemakers were developed to overcome these limitations, however, data in high‐risk patients ineligible for transvenous systems remain limited.

Quadricuspid aortic valve with aortic regurgitation: a rare echocardiographic finding. [PDF]
We report on a middle-aged woman treated for chronic hepatitis C virus infection with pegylated interferon. Auscultation revealed a diastolic murmur and the peripheral signs of aortic regurgitation.

ABSTRACT Background Leadless pacemakers traditionally rely on femoral venous access, which may be limited in patients with unfavorable IVC anatomy, prior interventions, or situations where preserving femoral access is preferred. Internal jugular (IJ) access offers an alternative route, but real‐world data on IJ implantation of single‐ and dual‐chamber ...

Abstract Sympathetic nervous system activation is a hallmark of high‐altitude hypoxia, yet the afferent mechanisms remain incompletely defined. We examined the relative contributions of pulmonary arterial mechanoreceptors and carotid chemoreceptors – two excitatory pathways co‐activated by hypoxia – to sustained sympathoexcitation at altitude.

Abstract figure legend This randomized cross‐over trial (N = 12) addressed the hypothesis that selective reduction of pulmonary arterial pressure (i.e. manipulation of pulmonary arterial mechanoreceptor activation) during hypoxic exercise would reduce sympathetic outflow (muscle sympathetic nerve activity (MSNA)) in healthy humans.

Valvular Heart Disease and Its Association With Death in Advanced Heart Failure
Background Valvular heart disease contributes to symptomatic heart failure, but its prevalence and prognostic significance in advanced heart failure is not well understood. Methods This retrospective population‐based cohort study included adult residents

Aortic valve conserving surgery in patients with aortic regurgitation [PDF]
INTRODUCTION. In the last two decades, the vlave-conserving surgery of regurgitant heart valves has been evolving. The aortic valve-sparing operations have been developing rather over the last decade, despite the clear benefit of mitral valve repair has ...

Abstract figure legend Activation of both the metaboreflex via post‐exercise circulatory occlusion and the chemoreflex via acute and chronic hypoxia increased pulmonary artery systolic pressure. Coactivation of these reflexes further increased pulmonary artery pressure in an additive manner.
